There are 8 languages on the trains' digital signage to help support our passengers to know where they need to go Arabic, Chinese, English, Japanese, Korean, Russian, Spanish, and Vietnamese! They will announce which stop you are at, which stop is next and other helpful information.

Terminal Shuttle/Yellow Loop:

There is a Terminal Shuttle train also known as the Yellow Loop.

  • This connector will take you to each train station hub of the S, B, and A Gates and the N, C, and D Gates!
  • These stations are at the D and A Gates and you can even take a shuttle between the two stations if needed. From here it’s easy to get from one train loop to the other.

South Train Loop/Blue Loop:

A, B, and S Gates are all in the South End of the terminal. Almost every international airline operates out of the S Gates or is on the south end of the terminal 

  • The A station is across from Gate A3 and down the escalator bank 
  • The B Station is at the end of the concourse down the escalators from Gates B20/21
  • The S Station is below the concourse level of all the S Gates

North Train Loop/Green Loop:

D, N, and C Gates are all in the North End of the terminal. This loop serves most Alaska Airline flights operating out of C, D, and N gates. 

  • The D Gates Station is across from Gate D2 and down the escalators, the C Station is down the escalators by Gate C11
  • The N Gates Station is down below the concourse level of all the N Gates
